Hi everyone,
I'm currently studying for my calculus test tommorow and I have some problems which I have no clue how to solve.
1) Lim (cos 2x)^(csc^2 2x)
x-> 0
Any help at all is very much appreciated, as I truly have no idea how to get started this excercise.
I'm sorry for not saying this earlier but L'Hopitals rule is not allowed.

Ok so I got this one in the form (1-2sin^2 x)^(1/2sin^2 2x) but i don't know how to go on from there. I know i'm almost there but i don't know how to get rid of the 2x above, I know it's silly, but i just don't see it.
